Good Creep Resistance Kiln Refractory Andalusite Brick As The Lining And Checker
1. High cold crushing strength
2. High refractoriness under the load
3. Good creep resistance
Andalusute Brick has high cold crushing strength,high refractoriness under load, high thermal stability,good creep resistance and thermal shock resistance,It is alternative product for high aluminum bricks, used in the professional of the key parts of the furnaces.
Applications
Andalusite bricks are mainly used in the cooling wall of blast
furnace, chemical and ceramic industry, the door of coke oven, or
as the lining and checker of hot blast furnaces. Andalusite bricks are products that add some components of
sillimanite or andalusite and other trace elements to the
components of high alumina brick. This series of products has
excellent thermal shock resistance and high temperature creep is
greatly improved. Andalusite bricks are used in blast furnaces, air
heaters, torpedo type mixer.
